chapter 1-----diagram
1:configuration
2: main circuit
3: pulse wire connection (xs1—xs6)

Note :this controller is open loop ,so no need connect encoder feedback
signal .ECZ+ ,ECZ- are feedback of servo encoder ,which are used for home
position accurate .
4:input diagram (xs5)
Note :the input pin5---pin12 are the turret tool sensor ,all sensors (include
home sensor ,limit sensor ) are NPN model (normal open)
5: output diagram (xs6)

Note: output pin1 and pin2 are connected to inverter .pin1 is spindle forward
signal ,pin2 is spindle reverse signal .pin 5 lubrication out signal and pin6 cooling
out signal are connected to relays which control the cooling and lubrication AC
motor .the relay should be 24V DC.
6:spindle analogue signal output xs8
Note: there are 2 analogue signal outputs,DA-out1 and DA-out2.that not means
the controller can control two spindles .that because both of signal are
same ,the DA-out2 is for standby ,normally ,we just connect DA-out1to
inverter ,you can refer the above right diagram .
7:spindle encoder diagram xs12

Note: if the application is threading ,an encoder should be installed ,the
connection is above diagram .(other applications no need encoder)
chapter 2 Operation
1:go home point
Note: there are two home points ,one is program home point ,the other is
machine home point .
1) program home point :the steps as below
a:under main interface ,press home button
b:press SBK button ,then controller will show mode :program
c:press x and z button ,the x and z coordinate will flash , then press CAN
button ,the x and z coordinate will be 0
2) machine home point :
a:connect home point sensor follow the input diagram

b:at the main interface ,press home
c:press SBK button ,select home mode is machine
d:press start (for all axis go home together ),press x- or z-,only x axis go home
or z axis go home
2: MDI -------MDI just for test
A:at the main interface ,press MDI(F3)
B:press edit button
C:at the MDI interface ,make the program ,for example
M03 s1000
G01 x100 z200
X300
T0101
X10 z10
M30
D:after making program ,press start button ,the controller will work
chapter 3: how to load program (CNC OR NC file )
1) by usb line (connect pc with controller by usb line –the back of
controller usb port xs11) ,the steps as follow
a:press FILE button ,it will show as below

B:then press TO PC—F6 button
C:open you pc ,then you can find a u disk in your pc
D:open the u disk (H)

E:open the PROG folder ,and copy the NC OR CNC file to this folder
F:select NC or CNC file in controller
G:then press EOB button

H:after pressing EOB button ,the program loading is finished
2) copy program by flash drive
A:insert the flash drive to usb port that at the front of controller
B:press file button ,then select data traveler
C:then you can find the cnc file in controller

D:press F3-copy ,then press CAN button ,back to lock disk ,and enter prog
folder ,then press paste –F4 button
chapter 4 normal parameters setting
A:genl parameters setting list
001---008 Gear Numerator and Gear Denominator
This is gear ratio setting
The formula is that CMR/CMD =P/ (L×1000)
CMR: gear ratio numerator
CMD: gear ratio denominator
P: Pulses corresponding to one rotation of the motor
L: the ballscrew pitch
For example :x axis ,the mechanical gear ratio is 1:1,the pitch is 5mm,the
servo motor pulse /round is 10000,then
CMR/CMD=10000/5×1000=2/1,so the x Gear Numerator setting value is
2,the Gear Denominator setting value is 1,if the the mechanical gear
ratio is 1:3,then CMR/CMD=10000×3/5×1000=6/1,so the x Gear
Numerator setting value is 6,the Gear Denominator setting value is 1
Other sample :Y axis ,the pitch is 8mm,the step motor pulse/round is
5000,then CMR/CMD=5000/8×1000=5/8,so the x Gear Numerator
setting value is 5,the Gear Denominator setting value is 8
009—012 X---4 Fast speed
These setting are the speed of G0,the Max setting is 200000

021---027 x----4 software limit
These setting are according to the real distance of each axis ,for
protecting the machine
029---inp speed
This setting is the speed of G1/G2/G3,the max setting is 200000
032---035 x----4 backlash expiate
These settings are the backlash compensation of each axis
036 zero return mode
It is going home mode, the normal setting is machine mode. Actually, at
the home mode, press SBK button can shift the home mode
059 G code pre-treatment
The normal setting is “preprocess”
B:axis parameters setting
001---004 servo Alarmin elevel
These settings are 0
C:spindle parameters setting
013 spi encode bits
This is the setting of spindle encoder resolution ,for instance :1024
020 spi max speed
This setting is spindle motor rated speed
